The invention relates to the technical field of aircraft accessory design, in particular to an undercarriage stay bar unlocking actuator of an air spring, which comprises a controller, a motor driver, a brushless direct current motor, a hydraulic pump, an overflow valve, a shuttle valve, an oil injection one-way valve, an exhaust one-way valve, an exhaust one-way valve and an actuating cylinder, the air cavity piston divides the upper part of the actuating cylinder into an air spring and an oil tank, a piston rod is arranged in the actuating cylinder and divides the lower part of the actuating cylinder into an extension cavity and a retraction cavity, and the oil tank is communicated with the extension cavity through an oil tank bushing; the controller, the motor driver, the motor and the hydraulic pump are electrically connected in sequence. An inlet of the hydraulic pump is connected with the oil injection one-way valve, the exhaust one-way valve and the extending cavity through oil ways in sequence. An outlet of the hydraulic pump is sequentially connected with an overflow valve, a shuttle valve and a retraction cavity of the actuator cylinder through oil ways, the overflow valve is connected with an oil-injection one-way valve oil way, and the shuttle valve is connected with an exhaust one-way valve oil way through a damping hole.
